Description

Mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of mould that arm-tie does not take mould inside space and easy accessibility that separates.

Background technology

Existing a kind of mould is used for the mould that injection mo(u)lding has casting product stub bar, and this mould comprises upper mounted plate, stripper plate, caster, mother module core, an elastic component and a bullet piece.Mother module core is arranged in the caster, and upper mounted plate is provided with and waters inlet, and caster and mother module core are provided with and water the stub bar passage that is used for the cast molding of product stub bar that inlet is connected; One draws the material pin to be fixed on the upper mounted plate, and passes stripper plate and stretch into the stub bar channel, and elastic component one end is fixed on the stripper plate; The other end is conflict bullet piece fixedly, after the condensation moulding, and upper mounted plate and the die sinking of stripper plate elder generation; Draw the material pin to break away from stub bar, then, stripper plate and caster die sinking; Elastic component is replaced the bullet piece and is replaced stub bar disengaging stripper plate, thereby stub bar drops.

But the elastic component of above-mentioned mould and spring are arranged in the mould, take die space, and dismounting is inconvenient, increases die cost.

The utility model content

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of mould that arm-tie does not take mould inside space and easy accessibility that separates is provided.

For realizing above-mentioned purpose, the utility model provides a kind of mould, comprises that a upper mounted plate, a caster, a stripper plate, separate arm-tie with the male model plate and of the corresponding setting of caster.Upper mounted plate is provided with one and waters inlet, fixedly is equiped with on the upper mounted plate to draw the material pin; Caster is arranged at the upper mounted plate below, and caster is provided with and the said runner that is used for the product cast molding that enters the mouth and be interconnected that waters; Stripper plate is located between upper mounted plate and the caster; The corresponding caster below that is arranged at of male model plate is equiped with one between male model plate and the caster and draws glue, draws glue one end to be arranged on the caster, and the other end is fixed on the male model plate; Separate arm-tie and be fixed at the stripper plate outside, two ends are provided with and dodge groove on one and dodge groove once about the separation arm-tie; Wherein, draw material pin upper end to be fixed on the upper mounted plate, the lower end is passed stripper plate and is inserted in the runner, and upper mounted plate and caster one side fixedly are equiped with a positioning block, and locating piece can place separation the upper and lower of arm-tie to dodge in the groove relatively slidably.

As stated, the utility model mould is fixed at the stripper plate outside through separating arm-tie, does not take the mould inside space, and separates the arm-tie easy accessibility, thereby reduces die cost.

The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

See also Fig. 1 and Fig. 2, the utility model mould is used for moulding one product 200, and it comprises that a upper mounted plate 10, a caster 20, a stripper plate 30, separate arm-tie 50 with the male model plate 40 and of caster 20 corresponding settings.

Said upper mounted plate 10 is provided with one and waters inlet 11, fixedly is equiped with on the upper mounted plate 10 to draw material pin 31.

Said caster 20 is arranged at upper mounted plate 10 belows, and caster 20 is provided with and said inlet 11 runners 21 that are used for product 200 cast moldings that are interconnected that water.

Said stripper plate 30 is located between upper mounted plate 10 and the caster 20, draws material pin 31 upper ends to be fixed on the upper mounted plate 10, and the lower end is passed stripper plate 30 and is inserted in the runner 21.

The said male model plate 40 corresponding caster belows that are arranged at are equiped with one between male model plate 40 and the caster 20 and draw glue 41, draw glue 41 1 ends to be arranged on the caster 20, and the other end is fixed on the male model plate 40.

Said separation arm-tie 50 is fixed at stripper plate 30 outsides, separates arm-tie and is provided with and dodges groove 51 on one and reach and dodge groove 52 in two ends 50 about.

Wherein, upper mounted plate 10 and caster 20 1 sides fixedly are equiped with a

positioning block

12,22 respectively, and locating

piece

12,22 can place dodging in the

groove

51,52 of separation arm-tie 50 relatively slidably.

See also Fig. 1 to Fig. 4, the utility model mould injects the injection raw material of fusion when die sinking not from watering inlet 11; After the condensation moulding; Product 200 takes shape in the caster 20, the product stub bar 300 that condensation moulding lower end links to each other with product 200 in the runner 21, thus accomplish whole injection moulding process.

Then, carry out the die sinking operation, like Fig. 2,3, shown in 4; Die sinking in advance between stripper plate 30 and the caster 20, stripper plate 30 and upper mounted plate 10 move upward together, owing to draw material pin 31 lower ends to strain at product stub bar 200; Product stub bar 300 lower ends break away from product 200, are fixed on the stripper plate 30 through separating arm-tie 50, and stripper plate 30 drives separation arm-tie 50 and moves upward together; Caster 20 also is in the matched moulds state through the effect of drawing glue 41 with male model plate 40; Thereby the locating piece 22 of caster 20 under dodge to slide into down relatively in the groove 52 and dodge groove 52 lower ends, at this moment, draw material pin 31 pulling product stub bars 300 to break away from runners 21.

Then; Upper mounted plate 10 and stripper plate 30 die sinkings are dodged groove 52 lower ends when locating piece 22 is stuck in down, are fixed between caster 20 and the male model plate 40 through drawing glue 41; Caster 20 is motionless; Simultaneously, be stuck in down through locating piece 22 and dodge groove 52 lower ends, thereby it is motionless to make caster 20 pullings separate arm-ties 50; Be fixed on the stripper plate 30 through separating arm-tie 50, stripper plate 30 is also motionless, along with upper mounted plate 10 continues to move upward; Thereby the locating piece 12 of upper mounted plate 10 slides into the top relatively in last dodging in the groove 51; At this moment, draw material pin 31 to break away from product stub bar 300, product stub bar 300 drops; At last; Caster 20 and 40 die sinkings of male model plate, upper mounted plate 10 continues to move upward, and locating piece 12 pullings of upper mounted plate 10 separate arm-tie 50; Separating arm-tie 50 moves upward through locating piece 22 pulling casters 20; Overcome the plastics that draw glue 41 and the frictional force between the caster 20, to the complete die sinking of feature die, the ejecting mechanism (not shown) of mould ejects product 200.

In sum, the utility model mould is fixed at stripper plate 30 outsides through separating arm-tie 50, does not take the mould inside space, and separates arm-tie 50 easy accessibility, thereby reduces die cost.
